' COOLING APPARATUS.

Application filed March 30, 1925.

My invention relates to improvement in cooling apparatus and while primarily intended for merchants display case refrigerators, it is obvious that the device may be employed for any other purposes wherein it is found to be applicable. J

The primary objectof the invention is to provide a cooling apparatus of the type described. in a manner as hereinafter set forth, which will maintain its frigidity for a. long period even after suspending the operation of the refrigerating machine. Under such conditions requiring less frequent intermittent operations of the latter and reducing the cost of operating the cooling system to a minimum.

Further objects of the invention are to provide a device of the class stated, which is simple in its construction and arrangement, strong, durable and efficient in its use, positive in its action, and comparatively inexpensive to manufacture, install and operate.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of the claim hereunto appended without departing from the spirit of the invention.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views Figure 1 is a side View, partly in section, of a cooling apparatus in accordance with my invention.

Fig. 2 is an end View thereof.

Referring in detail to the drawingl denotes a continuous tubular spiral cooling coil, disposed horizontally and having its ends 2 and 8 adapted for connection with respective supply and return conduits of the refrigerating machine.

Extending through the coil 1 is a cylindrical reservoir 4, closed at each end by a threadably connected Cap 5. The diameter of the reservoir 4 is approximately commensurate to the inside diameter of the coil Serial No. 19,383.

1, and the reservoir 4 constitutes a carrier for the latter.

The cylindrical reservoir is supported in position by a pair of supports 6. The lower ends of the latter are adapted to be seated on and secured to the floor of the display case in which the device is mounted, and the upper ends of each is formed with a rectangular recess 7. Each of the caps 5 is integrally formed with an outwardly extend ing squared projection 8 which seats in the recess 7,-of respective supports 6, and prevents the movement of the reservoir 4 in any direction or in any manner.

It will, of course, be understood that the reservoir 4 may be supported or suspended in any suitable manner, other than the supports 6, as the latter are merely illustrative of what is now thought to be the best embodiment therefor.

The reservoir 4 is filled with a suitable brine solution 9 best adapted to absorb and maintain thefrigidity imparted thereto from the coil 1 during the operation of the refrigerating machine.

The reservoir 4 is provided with an inlet plug 10 and adrain plug 11 to facilitate the filling and draining of the reservoir without removing a cap 5, but replacement of the brine solution 9 is very rarely required- It has been found in practice that a reservoir filled with brine and employed in connection with a cooling coil as herein described and illustrated, will be cooled to a very low temperature by the associated coils during the operation of the refrigerating machine, and that the temperature of the reservoir will then maintain the coil at the required low temperature for a very prolonged period after the operation of the refrigerating machine is discontinued, thereby reducing the operation of the latter to a minimum, and providing for the economical operation of the cooling system.

What I claim is The combination with the tubular coolstituting a carrier for said coil, a cap threadception of respective cap projections for ably connected with each end of said 'reserfixedly supporting said reservoir, said reser' voir for closing said ends, each of said caps voir provided with a supply plug and a 10 provided with an outwardly extending drain plug, substantially as described and squared projection, a pair of supports, each for the purpose set forth.

of said supports formed at its upper end In testimony whereofI affix In si nature. with a rectangular recess adapted for the re- JOHN H. OfiRIS.
